I disagree with some of the specifications. My 240 was always quicker and faster than these numbers. I got 0-60 in 8sec and topped out at 124mph (stubbornly refused to do 125mph, but that was before I knew about popping the hood open).

I get 22mpg going to and from work and I think I could do better. The new Nissans I drive all get 40mpg+ on the highway

On my first cross-country trip in 1976, I averaged 27+ mpg. That was with the car completely packed with my gear; toolbox, footlocker, seabag, uniform bag and AWOL bag. That all equalled the weight of a second passenger. I still had the 4 spd back then and with the cam I had in the car at that time, 70mph was the most comfortable cruising speed. On one leg of the trip I drove from St Louis to Erie PA overnight (where I slept for 3 days), often touching 90mph. The whole trip, overall, still averaged better than 27mpg.

And by the way, Porky, your 4-Bbl carb is capable of giving better fuel economy than most other carbs. The primary jets are smaller than those on a standard 2-Bbl, and much smaller than the combined volume of two SU side-draughts.

So if you keep your foot out of it (and never open those two monstrous secondaries), you should get outstanding fuel mileage ~ much better than the rest of us can get with our "big" SUs.

Going to Rochester to the Zfest I got 26.5 mpg on the highway doing 70 - 80 all the way.

Miles per gallon is very cool and what not, but what really counts is SMILES per gallon....let's just say that my number is off the chart...

EXACTLY right.
Perfectly stated.

I blame the early 5 speed and 3.90! Definitely times where I can be easier on the go pedal

OK, you're probably right. My Z has always had a 3.90 [Z or ZX] differential in it and with the stock 4-spd (the one I had for my cross-country trips), 4th gear was direct-drive (1:1 ratio). Now it has a 5 spd and 5th gear is an overdrive, which means the driveshaft turns more than one whole revolution each time the crankshaft turns. That means I could *probably* get better cross-country mileage now, if I didn't play with it along the way.

Since then I have enhanced the L24 slightly over stock, which always costs a little more fuel. But the result is that I can pass all the cars on that mile-long Woodbridge uphill on Rte15 coming out of the tunnels in 5th gear without any hesitation. THAT is a wonderful feeling and always makes me smile and pat the dashboard at the top of the hill, with the speedo reading 70+.

I bet you do that just to hear the sound of your car in that tunnel
